Hi,       We have a kerberoized cluster and written a oozie job where from main workflow(workflow.xml) we are submitting the subworkflow(subworkflow.xml).        In Subworkflow we have shell script with below command.        curl -s --negotiate -u : "http://xxxx:8983/solr/xx_collection_shard1_replica3/select?q=xxx_TIME%3A%5B2018-07-30T00%3A00%3A00.000Z+TO+2018-07-30T23%3A59%3A59.999Z%5D&wt=json&indent=true&rows=0"          When it executing we are getting HTTP Status 401 - Authentication required error.        Same shell script are available in main workflow shell action and its working fine and returns us response.        Only we have problem when executing from subworkflow..         "Our obseration" is before each submittion of oozie job we do kinit. so main workflow taking the credentails from kinit.

Hi,   I like to understand what is the advantage of storing data in hbase and index in solr instead storing both data and index in solr itself for NRT based application.   Currently we have 4 node solr cluster where we have NRT usecase which index into the solr using the Solrj library.whose collection size is around 4 gb with 2 shard and 2 replica.   Is there any problem when the collection size grows while using solr for both data and index.   Thanks & Regards, J.Ganesh Kumar.     ...

Hi all,         With the below steps we are able to copy the hbase data from cluster to another cluster.   snapshot "SOURCE_TABLE_NAME","SNAPSHOT_NAME" bin/hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot SNAPSHOT_NAME -copy-to hdfs://DESTINATION_CLUSTER_ACTIVE_NAMENODE_ADDRESS:8020/hbase -mappers 16 disable "DEST_TABLENAME" restore_snapshot "SNAPSHOT_NAME" But the problem is Source cluster does not have access to the destination cluster namenode. To solve this we are planning to have one shared location which mounted in both cluster nodes and using those we are planing to do import and export the snapshot to avoid multiple time copy of the files since the hbase table data size is hug which is around 10TB of data.   Can you please tell me the command to  export the snapshot to the local mounted shared File location (instead of hdfs location) restore snapshot from the local   mounted shared file location. ( instead of hdfs location) Thank you, J.Ganesh Kumar ... View more
